In addition to this change I just pushed to wip-texlive a number of
changes that may lead to an even bigger number of rebuilds due to
changes in the svn fetcher and even more TeX packages.

(I noticed that the branch name “wip-texlive” was already taken by the
attempt to add a new importer, so I just cherry-picked that commit and
replaced the branch.)

I don’t know yet if it leads to practical improvements for users, but at
least it greatly simplifies the definition of texlive-* packages.

I have yet to double check the often unclear licenses of the
texlive-hyphen-* packages.  Other than that and the WIP commit by Pierre
at the tip I think these changes are very close to their final form.
